The market size of PO is projected to reach USD 297.09 billion by 2021,
at a CAGR of 7.82% between 2016 and 2021. Polyethylene (PE) type
accounted for more than 50% of the overall PO market, in terms of
volume, in 2015. PE is the most widely used polymer in the plastic
industry owing to its easy availability and cheaper processing
techniques in comparison to other polymers.

Injection molding is projected to the fastest-growing application of PE,
between 2016 and 2021. Injection molding processes provide numerous
advantages in achieving faster production rate, desired size and shape,
and reducing wastage. The growing packaging sector is accelerating the
demand for injection molding in the plastic industry, thus boosting the
overall PE market.
